Spiral Galaxy M81. Photograph courtesy NASA. Postcard design by Richard Anderson. This galaxy was first descovered by Johann Elert Bode in 1774 and is one of the easiest to see by amateur astronomers because of it's unususal brightness in the night sky. Recent obervations have determined that M81 may contain very little dark matter compared to most galaxies. NOTE: this image was enhanced and brightened for artistic effect. Courtesy NASA.
